Numerology is a modular sequencing and audio plugin environment for Mac OS X. It takes sequencing and modulation metaphors established by the analog sequencers of the 70's, and implements them in a structured and highly interactive software environment designed for experimentation, improvisation and live performance. By using Numerology in conjunction with your choice of Audio Unit plugins and hardware synths, you can create an open compositional environment that is truly your own.

Not happy with the same-old even-division based sequencing stuff? Then try Numerology 1.4's new custom clock division capabilities. You can define any division of a beat from 1/1 to 32/32. That not enough? Then modulate your custom divisions with ParamMod for even wackier effects.

Triple X-Y Module

Not quite your garden-variety XY Controller, this module adds constant-time glide for building smooth parameter changes, long-form transitions, or --with the help of an LFO or two-- complex generative sequences.

Other Cool Goodies:

Groove Clock

Numerology version 1.3 adds powerful new tempo and timing controls in the form of the GrooveClock module. In addition to allowing you to tweak timing at the level of 16th notes, you can assign modulators to tempo, or even use multiple clocks. With this clock, swing-time is just the beginning.

MIDI Input

The new MIDI Input module allows you to setup Numerology as a virtual synth rack. Or you can use this module to drive the arpeggiator modes in the Matrix Sequencer, or to generate control information for other twisted purposes.

Matrix Sequencer

This flexible grid-based sequencer can be used to create polyphonic or monophonic sequences, or used for drums. It can also be used as an arpeggiator, complete with note sorting and latch modes.

Audio Unit Hosting

Numerology lets you run Audio Unit synthesizers and effects directly in the program, including mixdown of multiple instrument groups to a stereo output. In addition to the selection of Apple AUs included with OS X, you can add AUs from the growing number of commercial and free-ware Audio Unit synths, samplers and effects. Create a virtual studio that is truly your own. An up-to-date list of AUs is available at osxaudio.com.

Included among the standard Apple AU offerings are a DLS/Sountfont sample playback engine (complete with a custom Numerology interface) high-pass, low-pass, and band-pass filters, high and low shelving filters, graphic and parametric eq's, and delay and reverb modules. All the basics to get you started. Even if you never add another AU to this selection, the creative use of parameter modulation and sequencer programming can quickly take you into uncharted musical territory.Parameter Modulation

Numerology's Parameter Modulation module allows you to quickly add automation to almost any module parameter, including Audio Unit parameters. This seemingly simple addition opens up a world of new possibilities for sequencing and timbral manipulation:

* Create chaotic sequences by using one sequencer to modulate the start position or clock division of another sequencer. * Modulate parameters on AU synths and effects to create phrase-level timbral changes. * Integrate sounds from your hardware and software synths by modulating both from the same control source, by using both parameter modulation and CC or NRPN output. * Explore the world of glitch by modulating non-continuous parameters, such as some delay and reverb parameters on Apple AUs. * Create complex control values that you can perform in real time by modulating LFO parameters from another LFO or sequencer, and assigning key parameters to be controlled by a hardware fader box.

LFO Module

The Dual LFO module is a great source for generating control signals, either to generate pitch or velocity values for notes, act as a control source for Numerology's MIDI CC or NRPN output modules, or to modulate other parameters. This module includes two low-frequency oscillators that each have a number of powerful features:

Pulse width control over all waveforms LFO period programmable in increments of 1/16 notes, beats or measures, for LFO times as long as 100 measures, or directly in Hertz. Controls for waveform level, starting phase, rectification and inversion. Hard Sync setting, to automatically reset the LFO in time with your music. All parameters can be modulated to create complex waveforms.

And There's More...

* Sequencer triggering features make it easy to setup fill patterns, or other 'sparse' textures. * You can now setup MIDI remote control over group-level volume, mute & solo. You can also setup MIDI control of important sequencing parameters (such as clock division) across all sequencers in a group. * Numerology has two options for UI graphics: a lighter, 'Metal' UI (shown above) for daytime and contrast-challenging conditions, and a darker 'Studio' UI for use in low-light situations. * An updated sync reception algorithm improves sync to MIDI clock when using unstable sources, and avoids drift over long periods.

Many little things here and there, as well as support for running Numerology 1.X under Rosetta on Intel Macs, and PDF-formatted documentation.

* Fixed an Audio prefs issue that caused a crash under Rosetta. * Fixed a preset save bug that would cause the preset save dialog to appear twice. * Fixed a bug in saving pan info. * Fixed a bug that kept Numerology from launching in Panther. * Fixed a bug where pan was not saved/restored with a file. * ProgChange module changes: o The "ProgramNum" parameter can now be automated. o Each time the "ProgramNum" parameter is changed, it will send out a program change msg. * Added a hidden pref to disable transmission of MIDI song pos ptr, which should be needed only in rare circumstances. * The MidiSwitch & SignalSwitch modules should now work correctly. * Handling of CC control over the ctl seq module has been tweaked to ensure that incoming values are quantized when appropriate, and so that the UI does not display a value different from what the sequencer outputs. * Fixed a bug that could cause a crash when deleting a group. * This build seems to work fine in both 10.3.9/Quicktime 7 and 10.4.1. * Most of the UI controls in this version have been revised to avoid various drawing errors that occurred with earlier versions. * When setting factory presets for AUs, Numerology now sends both preset number and name. Some recent AU's crash if you don't also send the name (which according to the AU spec, should be optional for factory presets). * "mouseMoved" events are now turned on for AU edit windows, this allows mouse-overs and menus to work more smoothly. In particular this was an issue w/ NI plugins. * Plugsound free now seems to work correctly. Hopefully this will translate to other plugins based on the UVI engine.
